Property Tax Calculator
Property tax is usually quoted as a rate on assessed value, but you pay it monthly inside your escrow. This converts one into the other.
Use the monthly number when comparing two houses in different districts — the annual difference is easy to underestimate.

How it works
Annual tax = assessed value × the rate as a decimal (so 1.1% is 0.011). Monthly = annual ÷ 12, which is the amount a servicer collects into escrow each month.
The ten-year figure holds today's rate and today's assessment flat, then multiplies by ten. It is a budgeting yardstick, not a forecast: reassessments and rate votes are what move it in real life.
This is the tax line only. Homeowners insurance, mortgage insurance and any escrow shortage are separate amounts on the same monthly payment.
Example
$420,000 assessed value · 1.1% annual rate
- Annual property tax: $4,620.
- Monthly escrow collection: $385.
- Ten years at today's rate: $46,200.
- A 0.1 percentage point difference on the same house is $420 a year, or $35 a month.

Property Tax Calculator FAQ
How is property tax calculated?
Assessed value multiplied by the local tax rate. A $420,000 assessment at 1.1% comes to $4,620 a year, or $385 a month collected inside your escrow.
What is a normal property tax rate?
U.S. effective rates run roughly 0.3% to 2.2% of value depending on state and county, with a large share of places clustered near 1%. Always price the county, not the state average.
Is assessed value the same as market value?
No. The assessor's figure is what taxes are levied on, and it often lags the market or applies a fixed assessment ratio. That is why your bill can move on a different schedule from your neighbours' sale prices.
Why did my mortgage payment change if my rate is fixed?
Because taxes and insurance sit in escrow, not in the rate. When the annual tax bill rises, the servicer re-escrows and your monthly payment goes up with it — no rate change involved.
Do I still pay property tax after the mortgage is paid off?
Yes, permanently. Only the escrow goes away. You then pay the county directly, usually once or twice a year, which is why a paid-off house is not a no-housing-cost house.
Does this calculator include homeowners insurance?
No — it covers the tax line only. Insurance and any mortgage insurance sit on top, so your real monthly escrow figure is higher than the number shown here. Add them before comparing two houses.
